488 MR. E. A. SMITH ON NEW SPECIES OF SHELLS. [NoV. 17, 



lasali lutea ornata ; columella late expansa, oiliqua, nigres- 

 cens. 



Loncjit. 7 onillim., diam. maj. 3g ; apertura 3 longa, 2| lata. 



Hah. Common in rock-pools at Green Point, Watson Bay, Port 

 Jackson, N. S. Wales ; also Parsley Bay, Port Jackson {Brazier). 



Although of small size, the specimens described are evidently 

 adult. The species is remarkable for its produced acuminate spire, 

 the deep chestnut aperture bordered with a yellow outer lip, the 

 almost black columella, and the red and white punctate character 

 of the markings. This spotting is hardly visible to the naked eye, 

 and excepting under a lens the shell has a general dark slaty 

 appearance, yellowish at the suture and the base of the body- 

 whorl.

 Hah. Green Point, Watson Bay, Port Jackson. Found in rock- 

 pools washed by ordinary high tides (Brazier). 



This minute species like the preceding also appears to be adult. 

 It is generally almost black, excepting the basal spotted zone, but 

 occasionally specimens occur which are also more or less tessellated 

 above.
